Change wording

Add support for IPv6 counters to the RRD graphs. This adds 4 more data sources in the rrd file.
The graphing code colors are currently a mismatch and sorts waiting for someone with eyes to adjust to something useful
Other themes still need adjusting

Activate the firewall rules for DHCPDv6.
Add pass in to port 546, pass out to 547

adjust the firewall rules to allow for proper ICMP6 allow so that normal pmtu works

Remove duplicate advbase in ifconfig command

Merge remote branch 'upstream/master'

Conflicts:
etc/inc/system.inc

Show the TCP protocol for ipv6 filter rules

Move the ICMP rules further to the top in order for normal neighbour contact via icmp6 to work

Do not block fec0::/10 as this includes fe80:: local link addresses which breaks everything else

reference the IPv6 bogons table as well
